Telescope:
----------
- Ran Jon's NTD x-talk schedule twice
- 1 pointing schedule
Weather
--------
- Mostly good, few overcast periods
Cryogenics:
-----------
* Tracking spreadsheet at
http://bicep.rc.fas.harvard.edu/bicep2/south_pole_helium_usage/Summer_2011_…
* Kathleen's Cryo Sitrep:
LHe:
• Approximately 3200 liters of useable LHe remain in the Wessington dewars.
• Approximately 250 liters of LHe were delivered to BICEP2.
• Based on a historical consumption rate of 35.7 liters/day, LHe
supplies are expected to be exhausted by January 2013
GHe:
• Out of 16 storage tanks for gaseous helium: 8 tanks are at 17.2 MPa
(2500 psi), one tank is at 13.8 MPa (2000 psi), one tank is at 10.3 MPa
(1500 psi), one tank is at 7.8 MPa (1100 psi), one tank is at 6.9 MPa
(1000 psi), one tank is at 2.8 MPa (400 psi), one tanks is at 1.0 MPa
(150 psi), and two tanks are at 0 MPa (0 psi).
• Vent GHe from the LHe transfer was compressed into the storage tanks.
LN2:
• The liquid nitrogen plant off all week
• Approximately 350 liters of LN2 are currently stockpiled on station.
